FAQ
What does Mux do?
Mux keeps your Mac on the best network, automatically. It switches between connections based on your priority order, so when you plug in Ethernet, Wi-Fi steps aside, and when you unplug, it comes right back. See the Mux page for details.
Why would I need Mux?
When Ethernet and Wi-Fi are both active, macOS may route traffic unpredictably or cause IP conflicts. Mux resolves this by switching to whichever connection you have ranked higher and disabling lower-priority ones, giving you a cleaner, faster network setup without manual toggling.
Will Mux mess up my network?
No. Mux only enables and disables network services based on your configured priority. Your saved Wi-Fi networks, passwords, and DHCP configuration are never touched.
How does Mux decide which network to use?
Mux follows the service priority you configure in Settings. When a higher-priority network comes online, Mux waits for your configured delay, then switches to it and deactivates lower-priority connections. If your current network disconnects, Mux activates the next available connection immediately with no delay.
What is the difference between Turn Off and Disconnect?
When Mux deactivates Wi-Fi, it can either power down the Wi-Fi hardware entirely or just disconnect from the current network. Powering off is more reliable for reconnection. Disconnecting keeps the hardware on so AirDrop, Handoff, and AirPods continue to work, but Wi-Fi may not rejoin automatically in some cases.
What is Preferred Network?
Preferred Network is a temporary override that lets you pick a specific connection from the menu bar. Mux moves it to the top of your priority and switches to it. When you clear the override, your original order is restored.
What happens if Mux quits unexpectedly?
Your network stays in whatever state it was in. If Wi-Fi was off, it stays off until you turn it back on manually or relaunch Mux. Nothing is left in a broken state.
Does Mux phone home or track anything?
Mux processes everything locally on your Mac. The only network activity is license activation and periodic validation. There are no analytics, no telemetry, and no personal data collected. See the privacy policy.
How does pricing work?
One-time purchase, no subscriptions. A 7-day free trial is included so you can try before you buy. See the Mux page for current pricing and plans.
How do I get my license key after purchase?
After payment, your license key is sent to the email address you provided at checkout. Open Mux and activate it in the app.
What version of macOS do I need?
Mux requires macOS 14 (Sonoma) or later.
